    you just don't get the point. it was right to remove all the graphic part of CDNA because it used a lot of transistors.
    and the point about chiplet design is this: one big cpu/GPU die in the same performance is more expensive to produce than a chiplet design with 2 smaller chips.
    this means it makes sense to remove graphics from CDNA but it also make sense to make chiplet design or dualgpu with one RDNA chip and one CDNA chip. because chiplet design means lower costs and CDNA also means lower costs for compute (because less transistors compared to RDNA)

    "currently a massive shortage of available chips"

    and you see this wrong to... on the same silicon waver you can produce more chips if you do small chips in chiplet design compared to big chips.. this means this solution does in fact fix the shortage.

      the point is this: to make chiplet design for graphics means RDNA is very very hard.
      but make chiplet design with CDNA for compute is very easy.

      but chiplet lowers the costs compared to monolite bigger chip

      this means: if you make hybrid chiplet design with one RDNA and one CDNA chip you could run graphic on RDNA and the compute parts on CDNA... and Games could use it to because modern games like cyberpunk 2077 use more and more AI and deep learning features and complex physic... this means you can do thison the CDNA part and do only graphics on the RDNA part.

Meaning ignoring issues, bug reports, responding to people with prepared one line responses etc, more false promises.
        It's time to cut our losses and jump ship before it sinks and takes us with it. I'm selling my hw.
        I wonder if we all didn't put so much faith in AMD if we could have lobbied Nvidia to release an open source driver by now.
        Instead we've put all our eggs in one basket. The basket fell and we ended up with all our eggs broken.
        Vega64 and radeon7 runs well... and they work on RX5000 and RX6000 series but it is not done yet.
        what is your problem? they even hire people to do even more work.

        it is not what they want to do in the future it is the reality that the driver for RX5000/RX6000 is not ready yet.

        but thats not a big problem if you know this then you buy vega64 or radeon7 and you wait until RX5000/6000 is done.

        no one stop you to buy cards like this: Vega 10 XT (vega64)
        ✔ Preisvergleich für AMD Radeon Pro WX 9100 ✔ Produktinfo ⇒ Anschlüsse: 6x Mini DisplayPort 1.4 • Grafik: AMD Radeon Pro WX 9100 - 16GB HBM2 - Desktop • Chip: Vega 1… ✔ PCIe ✔ Testberichte ✔ Günstig kaufen


        and this: AMD Radeon Pro VII, 16GB HBM2, 6x mDP VEGA20 GLXT
        ✔ Preisvergleich für AMD Radeon Pro VII ✔ Produktinfo ⇒ Anschlüsse: 6x Mini DisplayPort 1.4 • Grafik: AMD Radeon Pro VII - 16GB HBM2 - Desktop • Chip: Vega 20 GL… ✔ PCIe ✔ Testberichte ✔ Günstig kaufen


        i do have a vega64 and i do not have any problem...

I have this Radeon VII, i'm tired of watching it glow red while its 14 teraflops go unused. I get more Gflops out of my Jetson Nano! I'm thinking of selling the RVII, living on a crappy old 1030 card I have lying around until Intel brings their stuff to the party.
          I'm very disappointed and my long, long support of AMD has taken a very serious beating.
          send the Radeon VII to me ;-) would be a nice upgrade for my Vega64.

            You think you don't. Install ROCm and go test Blender, DaVinci Resolve or Natron. Let me know if you still think you don't have a problem.

            I have this one but 8GB, not 16:

              It is understandable why users notably those running on Ryzen APU felt disappointed about the ROCm statement after years on waiting on proper support of open sources OpenCL. Focus should be on Mesa all along for desktop applications.

                *sigh*

                Stuff like this is why i quit posting to Phoronix. I think i came back too soon.

                  I think this feeds a bit on part of what I mentioned. There's some "define 'install ROCm' " sort of deal, as it's really a pretty big suite of things (there's the driver, utilities, HIP, 3 or 4 clangs(?)....). From the context I assume what you mean is the ROCm OpenCL drivers? I used to use that for quite a while and then one day they just stopped showing on clinfo so I know the frustration, for sure. Lucky for me the AMDGPU-PRO OpenCL drivers I get from the aur (as I run Arch on my home machines) works fine for me but still... not confidence inspiring.

                  I sometimes want to go back and rebuild everything, see if I can update things and make them work but then I realise I'm not even sure where to start trying that =)
                  In a way, thank you AMD for protecting me from myself keeping me away from that rabbit hole, I guess? A silver lining, perhaps

                    I tried with Blender. ROCm would cause the card to fall asleep every 0.1 seconds reducing performance to slower than CPU rendering.
                    I tried with Natron. It's a lie; Natron doesn't even use the GPU at all, and if it claims to do so then it's more of a lie because when I used it, it would use the CPU 100% of the time.

                      As stated before: use the binary driver for now (you can install only OpenCL and use the rest from mesa). Its OpenCL code (rocm-based) will be released to rocm git repo, soon.
